FYI - Conundrum is closed?
Never went to this place in Harvard Square - saw a "for lease" sign walking by the other day. Bad location to be sure...and I don't recall any great praise. Not really a conundrum if you ask me.
The place that preceded it, Iruna, was there for a really long time, perhaps as long as 20 years, as I remember the restaurant as far back as the mid-1980's. But then again, they were really cheap, good, and filled an unusual cuisine niche (Spanish non-tapas) for the area -- which might have contributed to their staying in business in an off-alley location.
No idea if Conundrum was good or not -- never got there.
